To all whom it may concern:

Be it known that l[, MAURICE 1L. STANARD, a citizen of the United States, residing at Kansast3ity,,inthe county of Jackson and 7' State of Missouri, have invented certain new and useful Improvements in Oil-Burma ing Apparatus, of which the-following is a apparatus that will supply a suficient volume and constant flow] of compressed air,

spray into the rapidly moving air, oil in fine. particles, heat the air and finely separated oil to a high temperature so that the a1r Wlll be thoroughly mixed with and saturated by the resulting oil gas and reach the burning orifices of the burner at high temperature.

By spraying the oil into the air of combustionand then passing the resulting mixture between heated surf-aces of metal vaporization is perfect and'the resulting gases are at a much. higher temperature on reaching the burner orifices, which results in high economy and a very blue hot flame.

The term oil is employed throughout this application and in the appended claims to: designate gasolene, naphtha, coal oil, distillateand all'liqu'id fuels to which the apparatus may be adapted and in connection with the burning of which the apparatus can be employed. A

The invention seeks to provide a simple and efficient apparatus'for vaporizing and form and structure of burning oil, by spraying the oil into the air of "combustion, subjecting the resulting mixture to a high temperature and delivering it while thus hot to the burning orifices of the burner. I

' With these and other objects view the invention consists in the features of construction, combinations and arrangements of parts hereinafter set forth and more par- .ticularly pointed out in the appended claims, the accompanying drawings illustrating a the oil burning apparatus. y

In the drawings Figure 1. is a view in elevation of the improved oil burning apparatus, with certain parts broken away to show the interior. K

Fig. 5 is a fragmentary perspective view of the separating rings oft-he burner.

The fuel supply tank 7 of usual construction is elevated above the fuel feed tank 8 and connected thereto by the common gravity fuel feedgpipe 9 inwhi ch is the filling valve 10.

v i The fuel feed tank 8 is of common construction and provided with the ordinary gage cocks 11, 1 2 and 18 as means of ascertaming approximately the quantity of oil in the tank, the usual practice being to open the cock ll' and close or allow to remain closed, the cocks 12 and 13, open the valve 10 and allow the oil to flow to the fuel feed I tank until it flows from the cock 11, when ing to test the'tank to ascertain whether there is oil in it.

Compressedv air is delivered to the fuel I the latter is closed, the cocks 12 and 13 beabove any oil that may be therein, the ordi nary pressure gage 17 being provided to in-- dicate the pressure in the tank and the com m'on pop valve 18 to allow any excess of pressure to escape.

The fuel feed pipe 19 is secured to the fuel feed tank 8 by the fitting 20 and extends down inside the tank to near the bottom 21 thereof and is connected to the nee dle valve 22 from which the spray tube 23 connects through the bushing 24: and extends through the "'1' fitting 25 to the mixing chamlbe'r pipe 26 the tube being capped by the nozzle 27, the pipe 26 connected by the coupling 28 to the extension mixing chamber pipe 29 and the wire screen 48 inserted. between the connecting ends of the pipes within the coupling. The pipe 29 connects to the reducing lfitting 30 from which the fuel and air mixture conducting pipe 31 connects to the retort 31 formed by the lower annular trough 32 and the upper annular from the fuel feed tank 8 to the T fitting 25 and provided with the air regulating valve 35.

The annular troughs 32 and 33 are secured together by the screws 37 and to the upper closed plate 36 of the. burner by the screws 37, the latter plate being secured to the lower plate 38 of the burner by the bolts 39, and the lower plate 38 is provided with the downwardly extending open mixing tube 40 preferably integral as shown.

' The mixing tube 40 is provided with. the downwardly extending arm 41 which supports the gaseous mixture pipe 42, the latter connetting from the retort 31*, formed of annular troughs 32 and 33 to and through this arm and provided with the L shaped nozzle 47 which is positioned to discharge the gaseous mixture approximately centrally into the mixing tube 40.

Between thevupper closed plate 36 and the lower plate 38 are the. upper and lower rings 43 and intermediate ring 44, the rings 43 being provided with the lugs 45 which separate the rings and the plates forming th orifices 46 from which the mixed and heated gases issue to the resulting flame.

In operation the'desired quantity'of oil is admitted to the fuel feed tank 8 and the motor 16 started supplying compressed air to the tank from the compressor 15, the air regulating valve 35 and the needle valve 22 are then opened and regulated so that the oil will issue from the nozzle 27 and the air from the tank 8 through pipe 34 will spray and partly vaporiz the oil, the resulting mixture passes through the pipes 26, 29 and 31 to and through the retort formed by annular troughs 32 and 33and then through the pipe 42 to thenozzle 47 from which the gaseous mixture flows through the mixing tube 40 gathering a small quantity of air through this latter tube by the suction created by'the flowing gases, the gaseous mixture and air spreading between the plates 36 and 38 and issuing from the orifices 46 where it is lighted and from which the flames burn.

As soon asthe flame is lighted the retort formed by the annular troughs 32 and 33 become heated and the mixture of oil spray and air is heated as they pass therethrough and become more thoroughly {mixed and gasified, the flames becoming very blue and hot when the retort becomes heated and the needle valve 22 and air regulating valve 35 are properly regulated.

What I claim as new, and desire to secure by Letters Patent, is

1. In oil burning apparatus, a disk shaped lower plate, an annular flange extending downwardly from said plate, a stepped shoulder formed in said annular flange, rings resting on said shoulder, lugs on said rings spacing them apart and forming circular orifices between the rings, a disk shaped plate resting on said rings, bolts binding said rings and said plates together, a circular retort resting on and secured to said upper plate, a mixing tube depending from said lower plate, means to supply air satnrated with oil to said retort, and a pipe leading from said retort downwardly and curved upwardly below said mixing tube.

I 2. In oil burning apparatus, a lower plate, an upper plate, rings between said plates, orificesbetween said rings, a mixing tube depending from said lower plate, a circular retort formed of annular troughs secured to said upper plate, means to supply-air saturated with oil to said retort, and a pipe leading from said re tort downwardly anld positioned to discharge in said mixing tu e.

3. In oil burning apparatus, a lower plate, a flange extending downwardly from the periphery thereof and then extending radially outwardly, rings resting on the radial portion of said flange, lugs on said rings separating them and forming orifices, a plate resting on said rings, bolts securing said plates together and gripping and holding said rings, an upwardly opening annular trough secured to said upper plate, a

downwardly opening annular trough isecured to said upwardly opening trough and forming a closed retort. a mixing tube depending from said lower plate, a tube lead-.

ing from said retort and positioned to discharge into said mixing tube, and means to supply said retort with air saturated with oil.
